Earth Crack

In the tomorrow people, the earth's equator is slightly damaged with a crack spanning half way around the globe and deep to the core. It is a direct gateway to Agartha, a legendary city deep within the core. No living being is able to enter Agartha via the crack, however Sam did in The Breakout part 2, but was saved by Ben. Eregon was trapped in Agartha in 7986 BC, so other shape shifters decided to save him by detonating a large bomg around the world's equator, opening the gateway.



Creation
The crack was created via a time paradox when Eregon was sent inside the Earth's core at the end of The Breakout. Others of his species located Eregon in the core and detonated a large bomb around the equator to bust out Eregon. It healed over time but left a deep crack spanning half way around the globe. The crack is never fully fixed and will always remain.

Extra info
As revealed in Army of the Empires, the crack goes through America and Japan, one of the main reasons the war was declared.
